Abstract This paper presents a novel approach to hyperchaos control of
hyperchaotic systems based on impulsive control and the
Takagi--Sugeno (T--S) fuzzy model. In this study, the hyperchaotic
Lü system is exactly represented by the T--S fuzzy model and an
impulsive control framework is proposed for stabilizing the
hyperchaotic Lü system, which is also suitable for classes of
T--S fuzzy hyperchaotic systems, such as the hyperchaotic
R?ssler, Chen, Chua systems and so on. Sufficient conditions for
achieving stability in impulsive T--S fuzzy hyperchaotic
systems are derived by using Lyapunov stability theory in the form
of the linear matrix inequality, and are less conservative in
comparison with existing results. Numerical simulations are
given to demonstrate the effectiveness of the proposed method.
